One of these "so-bad-it-is-good" movies. In the first half it's just boring, a badly done thriller. In the second the story (and acting and directing) gets so ridiculous i was laughing my balls off. Watch out for a "shocking" scene in which a hand has an important role. That must be one of the most creative scenes in film history. You'll know what I mean when you see it.
